DOPAK 密闭取样系统 　　由于工业制程的日益繁复，不论在一般工业或是石化和制药的专业制程上，对于取样测试和分析的需求将是持续增加。 　　在确定产品的鉴定工作上，代表性样品扮演了非常重要的角色。直接从制程上取样经常会使得操作员暴露在危险环境下，或是样品受到污染以及样品污染大环境等的隐忧。 DOPAK 取样方式就是以它的专利设计和操作方法来减低上述的困扰。 　　使用DOPAK 的密闭取样系统，操作员在取样时可避免与样品直接接触，可减少样品的溢出现象，并且可防止挥发性物质进入大气，取样的安全性获得极大的改善。

Due to the growing complexity of the industrial processes in general and more specific for processes in the petrochemical and pharmaceutical industries, the need for tests and analyses increases continuously. The need for representative samples plays a critical role in ensuring product verification. Yet sampling directly from the process often includes the risks of exposure to the operator, as well as contamination and pollution to the environment. The DOPAK sampling method reduces such risks with its patented design and simple method of operation. With DOPAK closed loop samplers for liquids, gas, liquefied gas and solids, the operator is shielded better from contact with the product being sampled. Local spillage can be avoided. Volatile substances are prevented from escape into the atmosphere. Safety in the widest sense is highly improved.
